Return to top of page. There are many structures used to organize classification schemes and there are many subject matter areas that classification schemes describe. So, this Part also provides a two-faceted classification for classification schemes themselves. Rationale for 3 rd edition:.
Part 2 Edition 3 should address use of Classifications, which is not within the scope of Two options were discussed for part 2: Withdraw or Split.
The published standards make no reference to editions, so withdrawing Part 2 could cause existing customers confusion or problems with compliance. The WG feels that a split to produce Part 2 Edition 3 WD to harmonize with Part 3 Edition 3 is needed, adding more explanation for creating and using Classifications, and adding references in the Bibliography to existing work on classifications.
This part should refer to content already covered in , not repeat it. The rationale for leaving this part in versus adding to TR is that existing users of expect to find information related to Classifications in , not somewhere else. Target date: TBD. Limit date: Related documents:.

A precise, well-formed definition is one of the most critical requirements for shared understanding of an administered item; well-formed definitions are imperative for the exchange of information.

It documents the standardization and registration of metadata to make data understandable and shareable. Organizations exchange data between computer systems precisely using enterprise application integration technologies. Completed transactions are often transferred to separate data warehouse and business rules systems with structures designed to support data for analysis. Data integration is often also solved as a problem of data, rather than metadata, with the use of so-called master data. The first principle from semantic theory is the thesaurus type relation between wider and more narrow or specific concepts, e. The second principle from semantic theory is the relation between a concept and its representation, e. A basic principle of data modelling is the combination of an object class and a characteristic.
